In order to understand why varicose veins are caused, we need to first understand how blood moves through the body. As everybody knows, blood is pumped throughout the body by the heart. Blood is supplied to the body through the arteries. Arteries are the pipeline which supplies nutrition through the blood, to various tissues in the body. After the blood reaches different points of the body, it will return to the heart. This is done through the veins. The problem starts form here. The reason is, blood flows through the arteries without any difficulties or restrictions. However, blood returning from certain areas of the body through the veins faces restrictions posed by gravity and other causes. Areas which are furthest away from the heart will experience more trouble. This is why most varicose veins are located in the legs. Veins contained in the legs have valves. This prevents the blood from pushing up again and dropping back under its weight. In order to avoid blood from building up in the veins, walking or exercising should be done. The problem arises when the person becomes inactive, thus leading to blood getting caught in the veins. Eventually over time, the veins can become deformed and start to swell up. In extreme cases it will become discoloured as well. This is why doctors say it is important to exercise or at least frequently walk to avoid them. There are basically 2 different ways a person can get varicose veins. One of them is hereditary. Some people are genetically predisposed to getting varicose veins. In most cases it caused by lack of exercise or movement. According to studies roughly 10 percent of people get affected by varicose veins. However, women face twice the risk compared to men. This is mainly because of pregnancy. A common symptom for varicose veins is brown coloured pigmentation of the skin. Other symptoms include night cramps and fatigue. In this day and age there are several varicose veins treatment options available for those of you who are suffering from varicose veins. However, VNUS Closure procedure is growing in popularity and for good reason. This is because this procedure is less painful and not as invasive as other vein stripping operations and treatments. The basic concept behind the VNUS closure procedure is simple and effective. The affected vein is shut off by inserting a catheter using RF energy. This in turn allows the blood to re-route itself through a healthy vein. The procedure is done with using local anaesthesia. It is also done as an outpatient therapy.
